64K mono would be about as crystal clear as 128 stereo, no? That's


You'd think , but DAB isn't that simple. I'm sure people more in the know
can correct me but AFAIK it doesn't simply send 2 channels of data for left
and right. I think like FM it sends mono data then some sort of difference
data which uses up much less bandwidth so a 128K DAB signal has a mono
component of something like (I'm guessing) 100K. I think this is why a lot
of people complain about the stereo image of DAB being very flat.

I'm sure wikipedia has more info.

crystal clear to most people. I listen to 32 K web streams which are
great for all but most critical applications.


DAB uses the MP2 codec from the late 80s. 32K would be unintelligable.
